[PATCH] slab: fix kmalloc_node applying memory policies if nodeid == numa_node_id()
kmalloc_node() falls back to ___cache_alloc() under certain conditions and
at that point memory policies may be applied redirecting the allocation
away from the current node. Therefore kmalloc_node(...,numa_node_id()) or
kmalloc_node(...,-1) may not return memory from the local node.
Fix this by doing the policy check in __cache_alloc() instead of
____cache_alloc().
This version here is a cleanup of Kiran's patch.
- Tested on ia64.
- Extra material removed.
- Consolidate the exit path if alternate_node_alloc() returned an object.
